Start With the Total Price — Then Drill Down
Genevera’s preferred sequence is to first ask whether the quotation is broadly within the expected Owner Estimate range. If the total looks abnormal in either direction, the next step is to understand why. Only after that first sense-check should the review move line by line through quantities, unit rates, inclusions and exclusions.
| Review Level | What to Check | Why It Matters |
|---|---|---|
| 1. Total quotation | Compare against BOQ/OE benchmark | Flags an abnormal commercial position quickly. |
| 2. Scope completeness | Check inclusions, exclusions and missing work | A low total can conceal future variations. |
| 3. Quantities | Compare measured quantities to drawings/BOQ | Quantity differences can materially change the total. |
| 4. Unit rates | Review rates item by item | Helps identify where pricing is driving the variance. |
| 5. Payment terms | DP, retention and payment structure | Commercial risk is not only about the tender total. |
A Quotation That Is Too Cheap Can Be a Risk
In tender comparisons, Genevera frequently encounters quotations that appear attractive at total-price level but contain exclusions, omissions or unusually low allowances. A quotation materially below the independent benchmark should therefore be treated as a review trigger, not an automatic winner.
The practical question is: what would have to be missing, under-measured or under-priced for the contractor to deliver the stated scope at that total? If the answer is unclear, the owner may face additional-work claims after construction starts.
Work Packages That Often Deserve Extra Attention
Based on Genevera’s tender and cost-comparison experience, the following packages often deserve closer review because unit rates or scope can materially influence the total:
- Wall works
- Floor finishes and associated works
- Swimming pool works
This does not mean these packages are always incorrectly priced. It means they are useful places to investigate when a quotation materially differs from the Owner Estimate.
Do Not Ignore Payment Terms
A competitive construction price can still expose the owner to commercial risk if the payment structure is weak. Genevera treats an unusually large advance payment and the absence of an appropriate retention mechanism as important points for review. The owner should understand what security, progress evidence and contractual protection support each payment milestone.
Case Example: When Similar Low Quotes Need Investigation
In one tender exercise, an updated Owner Estimate was approximately IDR 12 billion, while three contractor offers were around IDR 9 billion. The IDR 9 billion level was also close to an earlier version of the Owner Estimate. The similarity did not prove why the contractors priced at that level, but it was enough to justify a deeper review rather than assuming the low total represented the correct market cost.
The lesson is broader: when several bids cluster around a figure that appears inconsistent with the current scope and benchmark, owners should normalize the bids and examine quantities, rates, exclusions and specifications before award.
A Practical Quotation Review Sequence
- Confirm the drawings and specifications used by each bidder.
- Compare total tender price against the current OE/BOQ.
- Identify material variances rather than looking only for the cheapest contractor.
- Normalize exclusions and provisional items.
- Review quantities and unit rates for the largest cost packages.
- Review advance payment, retention and payment milestones.
- Clarify missing or ambiguous scope before signing.
Frequently Asked Questions
Should I simply choose the lowest contractor?
No. A low price can be competitive, but it can also result from missing scope, quantity differences, exclusions or aggressive assumptions. The quotation should be normalized against the same scope before award.
Is total price enough to compare contractors?
It is the first useful screen, but not the final decision. Once an abnormal total is identified, the owner should compare line items, quantities, rates and contractual terms.
Why is an Owner Estimate useful?
An independent OE gives the owner a benchmark that is separate from contractor pricing and helps identify where a quotation needs further investigation.
Important Note
This article is general construction cost guidance only. Actual pricing, contractual entitlement, valuation method, payment terms, guarantees, retention, variations and project controls depend on the specific project documents, scope, specifications and contract. Independent project-specific review is recommended before an owner makes a material commercial or payment decision.
